Good morning psalm 6819, I will answer your question by explaining how I became an American.
My great grandparents (maternal & paternal) crossed the Atlantic from Norway prior to and just after the civil war. They learned English, became legal and productive citizens. I, being native born, am a legal citizen by virtue of that fact. Now, I will wait for your explanation as to how this makes null and void the scripture verses quoted thus far.
Yes, as followers of Jesus we are to be a family, but when professing Christians try to include in this family of God "...them which say they are Jews, and are not, but are of the synagogue of Satan" (Rev. 2:9; 3:9) they need to be corrected. And, unfortunately, most people do not like to admit when they have been duped. For this reason they will cherry pick scripture texts. They will use a certain few scripture texts, those less clear in context,while ignoring a majority of texts pertinent to the subject and more clear. This will often include entire books of the Bible (Hebrews, James, 1Peter, etc.). These are the Christians (Dispensational-Futurists) whose interpretations create the illusion of Bible contradiction. But this seems not to bother them, until that is, someone reminds them that their interpretation is a contradiction of the Word of God. They will then show their respect for the scripture texts which contradict their interpretation---by trying to discredit anyone who explains them. When they cannot refute logic, reason, and proper exegesis they will resort to name calling ("anti-Semitic, hater, un-Christian," etc.).
So please, when I tell you that Hebrews, James, 1 Peter and others do not describe an Israel who rejected Jesus and the New Covenant do not try to destroy the messenger. Instead, do what Jesus said, "...search the scriptures," read, "search" these epistles for the idea that these Hebrew-Israelites were a non-Christian people (i.e., those you call "Israel").
